(d)1.81A

Explanation:

Answer 2

Below are given the answers to the following questions.

Explanation:

• Power consumed by geyser = 200 Watt
• Power consumed by CFL = 10 Watt
• Power consumed by TV = 250 watt

The formula of power:

P = I x V

Current "I" = P / V

Current "I" for geyser = 2000 / 20 = 9.1 A

Current "I" for CFL = 0.05 A

Current "I" for TV = 250 / 220 = 1.1 A

(b) Geyser

(c) Geyser is not suitable in home with a 5 A fuse because if we use it then the fuse wire of 5 A fuse will melt up and will result in circuit break.

(d) Current "I" fridge = 400 / 220 = 1.81 A
