Determine the work of the current in an electric lamp for 20 s at a voltage of 12 V at a current of 3.5 A.
| November 25, 2020 | education
The work of the current is equal to the product of time and voltage and current.
Given:
U = 12B
I = 3.5A
t = 20c
A =?
Formula:
A = t * U * I
Decision:
A = 20c * 12B * 3.5A = 840 J
