Answer 2

Dear Student,

◆ Answer -

(a) P = 48 Watt

(b) V = 12 V

● Explanation -

# Given -

I = 4 A

t = 10 min = 600 s

H = 2.88×10^4 J

# Solution -

(a) Power of the resistor will be -

P = H/t

P = 2.88×10^4 / 600

P = 48 Watt

(b) Voltage across the resistor is calculated by -

V = P/I

V = 48 / 4

V = 12 V

Hope this helps you dear...
