A 470
resistor, a 220 resistor, and a 100 resistor are all in parallel. The total resistance is approximately -
Five light bulbs are connected in parallel across 110 V. Each bulb is rated at 200 W. The current through each bulb is approximately
-
Four resistors of equal value are connected in parallel. If the total voltage is 15 V and the total resistance is 600
, the current through each parallel resistor is -
Five 100
resistors are connected in parallel. If one resistor is removed, the total resistance is -
Four 8
speakers are connected in parallel to the output of an audio amplifier. If the maximum voltage to the speakers is 12 V, the amplifier must be able to deliver to the speakers -
In a certain three-branch parallel circuit, R1 has 12 mA through it, R2 has 15 mA through it, and R3 has 25 mA through it. After measuring a total of 27 mA, you can say that

A sudden increase in the total current into a parallel circuit may indicate
-
The following currents are measured in the same direction in a three-branch parallel circuit: 200 mA, 340 mA, and 700 mA. The value of the current into the junction of these branches is
-
The following resistors are in parallel across a voltage source: 220
, 470 , and 560 . The resistor with the least current is -
