1

This circuit diagram represents a(n):

65% Answer Correctly

rectifier

parallel circuit

series circuit

series-parallel circuit


Solution

In a parallel circuit, each load occupies a separate parallel path in the circuit and the input voltage is fully applied to each path. Unlike a series circuit where current (I) is the same at all points in the circuit, in a parallel circuit, voltage (V) is the same across each parallel branch of the circuit but current differs in each branch depending on the load (resistance) present.


2

Which of the following is not a purpose of a resistor in an electrical circuit?

70% Answer Correctly

limit the current in the circuit

control the voltage in the circuit

moderate the heat in the circuit

multiply the current in the circuit


Solution

Resistors can be chosen in a wide variety of values to control the voltage in a circuit, limit the current, or moderate the heat produced by the components in the circuit.


3

You would measure the amount of current through a circuit with a(n):

68% Answer Correctly

voltmeter

ammeter

potentiometer

battery


Solution

Current is the rate of flow of electrons per unit time and is measured in amperes (A). An ammeter is used to measure the electric current in a circuit.


4 What's the overall power consumption of a piece of equipment that is rated for 9 amps at 90 volts?
80% Answer Correctly
802 W
812 W
810 W
814 W

Solution
Power is measured in watts (W) and 1 watt equals 1 ampere multiplied by 1 volt: P = \( V \times I \). For this problem, the equipment is rated for 9 amps (I) at 90 volts (V) so the equation becomes P = \( 90 \times 9 \) = 810 W

5

An engineer who wants to document an electric circuit would create which of the following?

67% Answer Correctly

a blueprint

a layout

a matrix

a schematic


Solution

A schematic is the proper name for a drawing of an electric or electronic circuit.
