Draw a schematic diagram of a circuit consisting of a battery of 12V, three resistors of `5ohm`, `10ohm`, and `20ohm` connected in parallel, an ammeter to measure the total current through the circuit, voltmeter to measure the potential difference across the combination of resistors.

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

A bulb whose resistance is 10 ohm is connected to a 6 V battery. Calculate the current through the circuit?

Draw schematic diagram of a circuit consisting of a battery of three cells of 2 V each a 5 Omega resistor: am 8 Omega resistor and 12 Omega resistor and a plug key, all connected in series?

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.

Three resistors of 4 ohms, 6 ohms, and 12 ohms are connected in parallel, and the combination is connected in a series with a 4 V battery having an internal resistance of 2 ohms. What is the battery’s current?
