Question

A series circuit has 4 identical lamps. The potential difference of the energy source is 60V. The total resistance of the lamps is 20 Ω. Calculate the current through each lamp.

Answer 1

`I=3A`

Step-by-step explanation:

From the question we are told that:

Number of lamps
`N=4`

Potential difference
`V=60v`

Total Resistance of the lamp is
`R= 20ohms`

Generally the equation for Current I is mathematically given by

`I=(V)/(R)`

`I=(60)/(20)`

`I=3A`
