Electrical Resistance


1 If the Voltmeter reading is 12V, and the Ammeter reading is 3A, what is the resistance?
36 Ohms
12 Ohms
4 Ohms
3 Ohms
4 Volts

2 What is the value of the resistor if a current of 2A flows when 8V is applied?
16 Ohms
8 Ohms
4 Ohms
2 Ohms

3 Now you need to turn the equation around.
How much current will flow through a 10 Ohm resistor when 30V is applied?
3 Amps
10 Volts
10 Ohms
30 Amps
300 Amps

4 What voltage is required to cause a current of 0.5A to flow through a 10 Ohm resistor?
0.5 Volts
5 Volts
20V
20 Ohms
5 Ohms
