How will you conclude that the same potential difference voltage exists across three resistors connected in a parallel arrangements to a battery?

Find the equivalent resistance of three resistors of 2Ohm,3Ohm,4Ohm when connected in parallel?

In the given circuit calculate potential difference across the lamp and resistor.

If potential difference across resistor is increased, will the current increase or decrease?

Study the following electric circuit and find potential difference across 4Ohm resistor

How is a voltmeter connected in the circuit to measure potential difference between two points?

Draw a circuit diagram of an electric circuit containing a cell, a key, an ammeter, a resistor of 2 ohms in series with a combination of two resistors (4 ohms each) in parallel and a voltmeter across the parallel combination. Will the potential difference across the 2 ohms resistor be the same as that across the parallel combination of 4 ohms resistors? Give reasons.
