easy
10 Questions
Question 1 of 10
What is the unit of measurement for electric current?
Electric current is measured in Amperes (A).
Question 2 of 10
What is the relationship between voltage (V), current (I), and resistance (R) in a circuit?
Ohms Law states V = I * R.
Question 3 of 10
What is the unit of measurement for electrical resistance?
Electrical resistance is measured in Ohms (?).
Question 4 of 10
If a circuit has a voltage of 12V and a resistance of 4?, what is the current flowing through the circuit?
Using Ohm's Law (I = V/R), I = 12V / 4? = 3A.
Question 5 of 10
What is the unit of measurement for voltage?
Voltage is measured in Volts (V).
Question 6 of 10
Which instrument is used to measure electric current?
An Ammeter is used to measure current.
Question 7 of 10
Which instrument is used to measure electrical resistance?
An Ohmmeter is used to measure resistance.
Question 8 of 10
If a resistor has a color code of Red-Red-Brown, what is its resistance in Ohms?
Red (2), Red (2), Brown (10^1) = 220 ?.
Question 9 of 10
What is the purpose of a resistor in a circuit?
Resistors impede the flow of current.
Question 10 of 10
How should an ammeter be connected in a circuit to measure current?
An ammeter must be connected in series to measure current.
