Could someone tell me how to start to solve this? Please
How much current flows in a 1000ohm resistor when 1.5 volts are impressed across it?

Use ohm's law:
voltage = current * resistance
arranging for current: current = voltage / resistance

OK but what would the current be 150 watts? volts?

Physics  Sheila, Saturday, October 27, 2007 at 10:52am
amps?

amps = volts / ohms
= 1.5/1000 amps
=0.0015 amps

The unit of currents is amps.

Ok but what is the answer how do i find the resistance? would it be .oo15 amps? this why i get so confused in this subject it all seems to run together.

Voltage is measured in volts, current is measured in amps, and resistance is measured in ohms. Ohms law says the relationship between these three items is:
V = I * R
where V = voltage in volts
I = current in amps
R = resistance in ohms
The equation can be rearranged to find resistance or current.
I = V / R
R = V / I
The problem gave two values, resistance and voltage. To find current, use the I = V / R equation.
I = V / R
I = (1.5 volts) / ( 1000 ohms)
I = 0.0015 amps
