Could someone tell me how to start to solve this? Please
How much current flows in a 1000-ohm resistor when 1.5 volts are impressed across it?
Use ohm's law:
voltage = current * resistance
arranging for current: current = voltage / resistance
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
OK but what would the current be 150 watts? volts?
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.
this helped me very much
To determine the current flowing through a resistor, you can use Ohm's Law, which states that the current (I) flowing through a resistor is equal to the voltage (V) across the resistor divided by its resistance (R).
In this case, you are given a voltage of 1.5 volts and a resistance of 1000 ohms. To find the current flowing through the resistor, you can use the formula:
I = V / R
Substituting the given values into the formula:
I = 1.5 volts / 1000 ohms
Now, let's calculate the answer:
I = 0.0015 Amperes (or 1.5 milliamperes)
Therefore, the current flowing through the resistor is 0.0015 Amperes (or 1.5 milliamperes).
