Question

A current 4A flows in a wire of resistance 60ohm . Calculate electrical energy consumed in2min

Answer 1

Hey friend
here is your answer

we have;

current = 4 A
resistance = 60 ohm
time = 2 minutes or 120 sec

voltage = current × resistance
= 4 × 60
= 240 V

$energy = voltage × current × time \\ energy = 240 \times 4 \times 120 \\ energy = 115200 \: joules$

glad to help you
hope it helps
thank you.

Answer 2

Given data:

Current (I) = 4A
Resistance (R) = 60Ω
Time (t) = 2 min = 120 sec.

Formula:

Electrical energy = Power x time
                             = I²R x t
                             = (4)²x60x120
                             = 16x7200
                             = 1,15,200 Joules or 115.2 Kilo Joules.
