An electric circuit contains an operating heating element and a lit lamp. Which of the following statements best explains why the lamp remains lit when the heating element is removed from the circuit?A The lamp has less resistance than the heating element.B The lamp has more resistance than the heating element.C The lamp and the heating element were connected in series.D The lamp and the heating element were connected in parallel.

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.

A student investigates the resistance of a lamp. The student uses a circuit that contains an ammeter, a battery, a lamp and a voltmeter to determine the resistance of the lamp. Draw a circuit diagram to show how he should connect the apparatus.

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.

The potential difference (p.d.) across a filament lamp is increased.Which statement is correct?A The resistance of the lamp decreases because the temperature decreases.B The resistance of the lamp decreases because the temperature increases.C The resistance of the lamp increases because the temperature decreases.D The resistance of the lamp increases because the temperature increases.
