Sam made some electrical circuits using identical lamps and batteries. Assist Sam to determine which circuithas the smallest current and which circuit has the brightest lamps respectively.A BC D(1) A and D (2) B and D (3) A and B (4) C and D

Which diagram most likely shows a circuit that will light up the bulb ?A.B.C.D

In which circuit did you observe a brighter light bulb?*1 pointCircuit with two dry cellsCircuit with one dry cellThe brightness of the bulbs in the two circuits are the same.The bulb did not light up in any of the circuits.

Girish had three rods made of different materials. He labelled them, X, Y and Z. He placedthem in the threedifferent positions, P, Q and R, as shown in the circuit below.He recorded the results of theexperiment in the table below. When any of the bulbs, B1, B2 or B3, lit up during theexperiment, he marked it with a tick (P) in the box.Based on the result givenabove, which classification of the materials, X, Y and Z, according to their electricalconductivity is correct ?A. 1B. 2C. 3D. 4

For a class project, Jerome builds a simple circuit with a battery and three light bulbs. On his way to school, Jerome drops his project and breaks one of the light bulbs. He has no time to fix or replace the bulb, so he removes the broken bulb and turns in his project. What will happen when Jerome runs current through his circuit?A If Jerome built a series circuit, both remaining bulbs will still light up.B If Jerome built a parallel circuit, both remaining bulbs will still light up.C If Jerome built a series circuit, only the remaining bulb closest to the battery will light up.D If Jerome built a parallel circuit, only the remaining bulb closest to the battery will light up.

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
