EEE :: Parallel Circuits

An ammeter has an internal resistance of 50 . The meter movement itself can handle up to 1 mA. If 10 mA is applied to the meter, the shunt resistor, R_{SH1}, is approximately

The total resistance of a parallel circuit is 50 . If the total current is 120 mA, the current through the 270 resistor that makes up part of the parallel circuit is approximately

The currents into a junction flow along two paths. One current is 4 A and the other is 3 A. The total current out of the junction is

When an additional resistor is connected across an existing parallel circuit, the total resistance

When a 1.6 k resistor and a 120 resistor are connected in parallel, the total resistance is

If there are a total of 120 mA into a parallel circuit consisting of three branches, and two of the branch currents are 40 mA and 10 mA, the third branch current is

Three lights are connected in parallel across a 120 volt source. If one light burns out,

Four equalvalue resistors are connected in parallel. Ten volts are applied across the parallel circuit and 2 mA are measured from the source. The value of each resistor is

A set of Christmas tree lights is connected in parallel across a 110 V source. The filament of each light bulb is 1.8 k. The current through each bulb is approximately

The power dissipation in each of four parallel branches is 1.2 W. The total power dissipation is
