A circuit with a 120-volt power supply is protected by a 10-amp circuit breaker. What is the largest number of watts loads on this circuit can safely use?

1200 W

Wattage is current multiplied by voltage: W = IV. So, the maximum amount of power a 120-volt circuit with a 10A circuit breaker would allow is 120 * 10 = 1200 W.

Which of the following is true regarding an AC signal?

The smaller the time period, the greater the frequency.

Frequency is the number of occurrences of an event per unit time. The relationship between the frequency and time period of an AC signal is \(f= \frac{\mathrm{1} }{\mathrm{T} }\) i.e. frequency is inversely proportional to the time period of an AC signal. The smaller the time period, the greater the frequency of the signal.

Which of the following statements about a capacitor is FALSE?

It is safe to touch a capacitor with your hands as long as it is small.

The purpose of a capacitor is to retain electric charge and it will do so even after its input voltage is removed. After the input voltage is removed, the capacitor will slowly discharge but, depending on the size and characteristics of the capacitor, discharging could take from a few minutes to a few years. So, it's never safe to touch a capacitor with your hands and you should make sure to discharge any capacitors in a circuit before working on it using an appropriately high-wattage resistor or a capacitor discharge tool.

How would you connect 8 [15V 25A] batteries to achieve a combined power output of 15V 200A?

parallel

Connecting the 8 batteries in series multiplies their voltage while keeping their current the same yielding a 120V 25A configuration. Connecting the 8 batteries in parallel multiplies their current while keeping their voltage the same yielding a 15V 200A configuration. Using a series-parallel connection, 4 batteries can be connected in series and 4 can be connected in parallel resulting in a 60V 100A configuration.

A microwave is consuming 800 W power using a standard North American 120 V power supply. What is the approximate amount of current flowing?

7 amperes

The formula for finding electrical power is Power = Voltage x Current or P=VI. Rearranged we have \(I= \frac{\mathrm{P} }{\mathrm{V} }= \frac{\mathrm{800} }{\mathrm{120} } = 6.67 \approx 7 \) amperes

In electrical wiring, which of the following are proportional?

the diameter of the wire and the amount of the current

Current flow through a wire increases the temperature of the wire. If too small a wire is used, the wire will heat up causing a loss in conductivity and possibly a fire. The thicker in diameter a wire is, the more current it can carry without overheating.

If two different resistors are connected in series, then which of the following statements is correct regarding the electrical power consumed by the resistors?

The resistor offering larger resistance will consume more electrical power.

If two resistors are connected in series then the current flowing through each resistor is the same because the current remains the same in a series. The formula for finding electrical power is P=VI. From ohms' law, we know that V=IR => I=V/R. Putting the value of I in the formula of electrical power will give \(P=R I^2 \). As current is the same through both resistors then electrical power is directly proportional to the resistance i.e. the bigger the resistance the higher will be the power consumed and vice versa.

What is the voltage in a circuit with 10 amps of current and 6 ohms of resistance?

60

The formula to use here is: \(V=I \times R=10 \times 6=60\)

Inductance is a factor in which of the following?

an AC circuit

Inductance is a property of an AC circuit (or a component in an AC circuit) that quantifies resistance to changes in current. The current in an AC circuit is continuously changing and inductive reactance (the opposition to change) depends both on the inductance of the circuit or component and the rate at which the current is changing.
