How much current flows through a 12 ohm resistor?

Answer and Explanation: The current flowing through the 12 ohm resistor is 0.47 A.

How much current will flow through a resistor of resistance 12 Ohm If a battery of 18 V is connected across it?

hence, 1.5 ampere current will flow through a resistor of resistance 12 ohm, if a battery of 18 V is connected across it.

How do you calculate current and resistance?

Ohms Law and Power

1. To find the Voltage, ( V ) [ V = I x R ] V (volts) = I (amps) x R (Ω)
2. To find the Current, ( I ) [ I = V ÷ R ] I (amps) = V (volts) ÷ R (Ω)
3. To find the Resistance, ( R ) [ R = V ÷ I ] R (Ω) = V (volts) ÷ I (amps)
4. To find the Power (P) [ P = V x I ] P (watts) = V (volts) x I (amps)

How to calculate watts from volts and ohms?

Watts calculation. The power P in watts (W) is equal to the voltage V in volts (V) times the current I in amps (A): The power P in watts (W) is equal to the squared voltage V in volts (V) divided by the resistance R in ohms (Ω): The power P in watts (W) is equal to the squared current I in amps (A) times the resistance R in ohms (Ω): Ohm’s law ►.

How to calculate Ohms Law in a calculator?

Ohm’s Law Calculator Voltage (V) = Current (I) * Resistance (R) Power (P) = Voltage (V) * Current (I) Enter any two known values and press “Calculate” to solve for the others.

How is the voltage of a circuit related to the Ohms Law?

Ohm’s Law Equation: Ohms law derived that the amount of current (I) through a metal conductor in a circuit is directly proportional to the voltage (V) impressed across it, for respective temperature.

How is the current I in amps equal to?

The current I in amps (A) is equal to the voltage V in volts (V) divided by the resistance R in ohms (Ω): The current I in amps (A) is equal to the power P in watts (W) divided by the voltage V in volts (V): The current I in amps (A) is equal to the square root of the power P in watts (W) divided by the resistance R in ohms (Ω):
