Question

240 joules of work is done in moving 20,coulomb electric charge from one pole of abayyery . Calculate the voltage of the bettery

Answer 1

Answer:

voltage ⚡ =12volts

Explanation:

energy/work=240J= power *time

power=voltage*current

current=charge/time

charge=20C

voltage ⚡ =?

energy =VIT (kwh)

voltage (V) =energy/((charge/time)*time)

Voltage (V) =energy/charge

voltage(v)=240/20

voltage ⚡ =12volts
