Exercise : Parallel Circuits - General Questions
6.
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
50 mA
70 mA
120 mA
40 mA

No answer description is available. Let's discuss.

7.
Three lights are connected in parallel across a 120 volt source. If one light burns out,
the remaining two will glow dimmer
the remaining two will glow brighter
the remaining two will not light
the remaining two will glow with the same brightness as before

No answer description is available. Let's discuss.

8.
Four equal-value 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
12.5
200
20 K
50
Explanation:

10/(R/4) = 2 mA

40/R = 2 mA

R = 40/2 mA

= 40/0.002 A

= 20000 kohm (20 kohm)

9.
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
610 mA
18 mA
110 mA
61 mA
