Two electric lamps are connected in parallel in a circuit with a voltage of 220V.

Two electric lamps are connected in parallel in a circuit with a voltage of 220V. Determine the current strength in each lamp, if the resistance of one is 1000 Ohm

Given:

R1 = 1000 Ohm

R2 = 1000 Ohm

U = 220V

l1 =?

l2 =?

Solution:

Current formula:

l1 = U / R1

l1 = 220/1000 = 0.22 A

l1 = 0.22 A

l2 = U / R2

l2 = 220/1000 = 0.22 A

l2 = 0.22 A

Answer: The current in each lamp, with a resistance of one 1000 Ohm, will be equal to 0.22 A.

The current in each lamp will be the same l1 = l2 /.
