YOUR ANSWER : ?
When an additional resistor is connected across an existing parallel circuit, the total resistance
YOUR ANSWER : ?
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
YOUR ANSWER : ?
When a 1.6 k resistor and a 120 resistor are connected in parallel, the total resistance is
YOUR ANSWER : ?
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
YOUR ANSWER : ?
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
YOUR ANSWER : ?
There is a total of 800 mA of current into four parallel resistors. The currents through three of the resistors are 40 mA, 70 mA, and 200 mA. The current through the fourth resistor is
YOUR ANSWER : ?
In a five-branch parallel circuit, there are 12 mA of current in each branch. If one of the branches opens, the current in each of the other four branches is
YOUR ANSWER : ?
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, RSH1, is approximately
