1. There is a 28 risistance in the heating element. It is the plugged into a
110 V circuit. how much current passes through the heating element?
2. A lamp operates t 115 V with a current of 0.45 A . What is the lamp's
risistance?
3. What is the resistance of a light if the voltage is 12.0 V and the current
is 30.A?
4. What is the total voltage in a circuit if the current passing through is .75 amps and resistance is 35

Answer:
1. I = V/R
= 110/28
= 3.92 amp
2. R = V/I
= 115/0.45
= 255.5 ohms
3. R = V/I
= 12.0/30
= 0.4 ohms
4.V = IR
= .75x35
= 26.25
