Question

how much current is drawn from a circuit that has a resistor of 1000ohms if powered by a battery with 1.5 volts​

Answer 1

Answer:

Given Voltage V=1.5 v

Given resistance R=1000 ohms

According to ohms law V=IR

1.5=I* 1000

I=1.5/1000

I=1.5 mA

Answer 2

Given: A resistor of 1000 ohms is powered by a battery with 1.5 volts.

To find: Current drawn by the circuit

Explanation: Let the resistance be denoted by r, current by i and voltage be denoted by v.

Ohm's law states that current drawn in a circuit is directly proportional to the voltage across any points if temperature and other physical conditions remains the same.

The formula used is:

v = ir where r is the proportionality constant according to the given law.

v= 1.5 V

r= 1000 ohm

Using formula:

i = v/r

= 1.5 / 1000

= 0.0015 A

Therefore, the current drawn from the circuit is 0.0015 Ampere(A).
