Examine the circuit below. Which of the following statements is false? A R1 R3 R2 All three resistors are connected in parallel. O The reading on the ammeter would be 'zero'. The reading on the voltmeter would be 'zero'. J This circuit has no current running through it because nothing is powering it.

Consider a circuit consisting of a battery and two bulbs. Explain why the following two statements are direct consequences of the preceding definitions. A. When two bulbs are connected in series, the same current that passes through one bulb must also pass through the other. B. When two bulbs are connected in parallel, current that passes through one bulb does not pass through the other.

The circuit shown has two resistors, with R1 > R2 .Which resistor dissipates the larger amount of power? Explain.

In the circuit below, if R5 is replaced by a resistor that is a third of R5, which one of the following statement about the currents in each branch is correct? R4 in RS O The only thing that will change is the current flowing through R5. O Changing R5 does not affect the currents in the circuit. O The only thing that will change is 1. O Current 11 will change, as well as currents flowing through R2, R3 and R5. O Currents flowing in R3 and in R2 will change but 11 will remain constant.
