Question

How to calculate voltage without knowing resistance?

Answer 1

voltage is equal to work done/ charge

Answer 2

Hey friend

Here is your answer
________________


•If the work done and charge is known then the voltage can be calculated as :

Voltage =Work done /Charge

V=W/Q
__________________________

•If the current and power is known then the voltage can be calculated as :

Power =Voltage ×Current

Voltage=Power/Current

V=P/I
