# Electrical Engineering - Parallel Circuits

Exercise : Parallel Circuits - General Questions
1.
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
55 5.5 50 9 Explanation:
No answer description is available. Let's discuss.

2.
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
22 mA
120 mA
220 mA
50 mA

3.
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
1 A
7 A
unknown
the larger of the two
Explanation:
No answer description is available. Let's discuss.

4.
When an additional resistor is connected across an existing parallel circuit, the total resistance
remains the same
decreases by the value of the added resistor
increases by the value of the added resistor
decreases
When a 1.6 k resistor and a 120 resistor are connected in parallel, the total resistance is
greater than 1.6 k greater than 120 but less than 1.6 k less than 120 but greater than 100 less than 100
