A portable electric heater has a resistance of 10 ohms. It plugs into a wall
outlet that is 120 V. How much current, in amps, does it draw?

The current in the electric heater is 12 A.

Explanation:

Current is directly proportional to the voltage flowing in any circuit and resistance of the resistor is the proportionality constant . This is in accordance with the ohm's law. So current can be determined by the ratio of voltage to resistance.  As the resistance is given as 10 ohms and the voltage is given as 120 V, then the current is

Current = V/R

As V = IR

Current = 120/10 = 12 A

So the current in the electric heater is 12 A.

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
