Question

Voltage of bulb 5 volt and current is 500 mamp. Find resistance , power and energy in 2.5 hour?​

Answer 1

Answer with Explanation:

V = 5v

I = 500 × 10^-3 = 0.5 amp

R = V/I

R = 5/0.5 = 10 ohm

P = VI

P = 5 × 0.5 = 2.5 W

E = P × t

E = 2.5 × 2.5 = 6.25 J

Answer 2

hello buddy

so here is your answer

voltage(v)=5 V

current(I)= 500 m A(500 milliampere)=500*10^-3=0.5 A

then to find resistance use ohms law

v=RI

=5=R*0.5

=R=5/0.5

=R=10 ohm

power= vI= 5*0.5=2.5 watt

then energy= Power(in Kwh) * time

                    =2.5/1000*2.5

                    =0.00625kWH

hope it helps buddy
