The diagram shows a circuit containing three ammeters P, Q and R.
Which statement about the readings on the ammeters is correct?
The reading on P is equal to the reading on Q.
The reading on P is equal to the reading on R.
The reading on Q is greater than the reading on P.
The reading on Q is greater than the reading on R.
Resistors of resistance 1.0Ω, 2.0Ω and 3.0Ω are connected in parallel across the terminals of a cell.
Which statement is correct?
The currents in the resistors are equal.
The sum of the currents in the three resistors is equal to the current in the cell.
The sum of the potential differences (p.d.’s) across the resistors is equal to the electromotive force (e.m.f.) of the cell.
The potential difference across the 3.0Ω resistor is greater than the potential difference across the other two resistors.
