Frequently Asked Questions - Source Voltage Calculator:
What is source voltage?
Source voltage is the supply voltage provided by a battery, generator, or power source to a circuit.
How do you calculate source voltage in DC?
Use Vs = I × R, where I is current and R is resistance.
How do you calculate source voltage in AC?
Use Vs = I × Z, where Z is impedance.
What is the unit of source voltage?
It is measured in volts (V).
Is source voltage the same as supply voltage?
Yes, both terms mean the same in electrical circuits.
Does load affect source voltage?
Ideally no, but in real systems voltage may drop under load due to internal resistance.
Can source voltage be measured directly?
Yes, using a voltmeter across the source terminals.
What happens if source voltage is too high?
It can damage connected devices or cause overheating.
What happens if source voltage is too low?
The circuit may not operate correctly or devices may underperform.
Is source voltage important for Ohm’s Law?
Yes, it is directly related to current and resistance as Vs = I × R.
