please solve last part of this question no. (e)​

Answer 1

Answer:

Bill = ₹0.8

Explanation:

Equivalent resistant in the circuit = 20 ohm

H = I²Rt

I = V/R

PUTTING value

H = V²/R t

H = 40*40/20*2

H = 160 Joule

H = 160 Watt hour

In kWh

H= 0.16 kWh

Bill = H*Rate

Bill = ₹0.8

Answer 2

Answer:

eqivalent resistance in circuit=20ohm

volte=40v

by ohm's law

v=ir

40=I*20=2A
