Question and answer
A circuit is wired with a power supply, a resistor and an ammeter (for measuring current). The ammeter reads a current of 24 mA (milliAmps). Determine the new current if the voltage of the power supply was ... a. ... increased by a factor of 2 and the resistance was held constant. b. ... increased by a factor of 3 and the resistance was held constant. c. ... decreased by a factor of 2 and the resistance was held constant. d. ... held constant and the resistance was increased by a factor of 2. e. ... held constant and the resistance was increased by a factor of 4.
f. ... held constant and the resistance was decreased by a factor of 2. g. ... increased by a factor of 2 and the resistance was increased by a factor of 2. h. ... increased by a factor of 3 and the resistance was decreased by a factor of 2. i. ... decreased by a factor of 2 and the resistance was increased by a factor of 2.

a. Inew = 48 mA (Current is directly proportional to voltage; a doubling of the voltage will double the current.)

Inew=24 mA * 2
Inew= 48 mA

b. Inew = 72 mA (Current is directly proportional to voltage; a tripling of the voltage will triple the current.)

Inew=24 mA * 3
Inew= 72 mA

c. Inew = 12 mA (Current is directly proportional to voltage; a halving of the voltage will halve the current.)

Inew=24 mA / 2
Inew= 12 mA

e. Inew = 6 mA (Current is inversely proportional to resistance; a quadrupling of the resistance will reduce the current to one-fourth its original value.)

Inew=24 mA / 4
Inew= 6 mA

g. Inew = 24 mA (Current is directly proportional to voltage; a doubling of the voltage will double the current. But current is also inversely proportional to the resistance; a doubling of the resistance will halve the current. These two factors offset each other and there is no overall change in the current.)

Inew=24 mA / 2 * 2
Inew= 24 mA

h. Inew = 144 mA (Current is directly proportional to voltage; a tripling of the voltage will triple the current. But current is also inversely proportional to the resistance; a halving of the resistance will double the current. So the new current can be found by tripling and then doubling the old current of 24 mA.)

Inew=24 mA *3 * 2
Inew= 144 mA

i. Inew = 6 mA (Current is directly proportional to voltage; a halving of the voltage will halve the current. But current is also inversely proportional to the resistance; a doubling of the resistance will halve the current. So the new current can be found by halving and then halving again the old current of 24 mA.)

Inew=24 mA /2 /2
Inew= 6 mA
