When two identical lamps in a circuit are connected in parallel, the equivalent combined resistance is​more than the resistance of either lamp.​Group of answer choicesTrueFalse

A simple circuit exists with one light bulb. A resistor of equal resistance to the bulb gets placed in the circuit in parallel. Which of the following would occur? The current would increase. The total voltage would decrease. The current would stay the same. The total resistance would remain the same.

Determination of the Equivalent Resistance of Two Resistors When Connected in Parallel

The total resistance in a parallel circuit is less than the smallest of the individual resistances.a.Falseb.True

A small bulb has a resistance of 2Ω when cold. It takes up a current of 0.4 A from a source of 4V and then starts glowing. Calculate (i) the resistance of the bulb when it is glowing and(ii)  Elaborate on the reason for the difference in resistance?

When electric charges flow through the wires and loads of the circuits they encounter resistance or a hindrance to their movement. So another factor that affects the flow of charges or current is resistance. The symbol for resistance is capital letter R. The unit, ohms (Ω) is named after the German physicist Georg Simon Ohm.In which circuit did you observe a brighter light bulb?*1 pointCircuit with one light bulbThe bulb did not light up in any of the circuits.The brightness of the bulbs in the two circuits are the same.Circuit with two light bulbs
