What is the amount of current in a circuit if the battery supplies 12 volts and the resistance is 3 ohms?
4 Amps
Suppose that three identical resistors with a resistance of 3-ohms are placed in series with a 12-Volt battery. The current in the circuit is 4 Amps.
What is the current through the 12 ohm resistor?
24/12=2 amps.
How many amps are in a circuit?
Every circuit breaker has a specified amperage (amount of current). This rating is labeled on the breaker itself. The standard for most household circuits are rated either 15 amps or 20 amps. An important note to remember is that circuit breakers can only handle about 80% of their overall amperage.
What is current in a circuit?
Current is the rate of flow of electric charge. It is not used up in a circuit; at all points in a series circuit, current has the same value. If a circuit has a branch, the current flowing into the junction must equal the current flowing out of it.
How many amps are in a resistor calculator?
The current through the resistor is 1.2 amps. If you want more examples, the resistor page has more fun than a barrel of monkeys. If you want to try a few for yourself, the calculators below will allow you to check your math.
How much power is flowing through a resistor?
The power dissipation in the resistor is 14.4 watts. If you wanted to know how much current was flowing through the resistor, you would use the formula: The current through the resistor is 1.2 amps.
How to calculate the voltage of a 10 Ma resistor?
[Voltage (V) = Current (I) x Resistance (R)] V (volts) = I (amps) x R (Ω) Find the voltage applied across 15 kΩ resistors when 10 mA current flows through it. Solution: Voltage (volts) = Current (amps) x Resistance (Ω); V = 10 mA x 15 kΩ; V = 150 V
How to calculate voltage and current in ohms?
Calculate voltage/current/resistance/power. Enter 2 values to get the other values and press the Calculate button: The voltage V in volts (V) is equal to the current I in amps (A) times the resistance R in ohms (Ω):
