How much current flows through a 3 ohm resistor?

How much current flows through a 3 ohm resistor?

Therefore, the current passing through the 3-ohm resistor is 4 amperes.

How much current flows through a 12 ohm resistor?

The 12-ohm resistor would have a current of 1 Amp (using Ohm’s law equation) and the 4-ohm resistor would have a current of 3 Amps (using Ohm’s law equation).

What is the PD across the 3 ohm resistor?

Hence the potential difference across the 3 ohm resistor will be 0.6 V.

What is the potential drop across the 3 ohm resistor?

1 volt
Hence, the potential drop across the 3Ω resistance is 1 volt .

What is the current in 12 ohm?

Explanation: 24/12=2 amps.

What is the resistance of a clothes iron that draws a current of 12 A at 120 V?

What is the resistance of a curling iron that draws 12 A of current on a 120 V circuit? R = v= 120v = 100 Gu . 1.1.

What is the current through the 6 ohm resistor?

In a series combination, the current remains the same. So the current through the 6 Ω resistor is 0.44 A.

What is the voltage when the resistance is 6 ohms?

Explanation: 8= E/6 voltage=8 x6 48 volts.

How do you find the voltage applied across a 15K 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

What is a 12V power supply with high current?

12V Power Supply – 30A. This is high current 12V power supply. Power supply uses LM7812 IC and can deliver up to 30A to the load by the help of the TIP2955 pass transistors. Each transistor can handle up to 5A and six of them result an total output current of 30A.

What is ohm’s law in circuit theory?

Ohm’s Law states that V=I*R, where V is voltage, I is current and R is resistance. In a series circuit, the voltage drop across each resistor will be directly proportional to the size of the resistor.

How many 1/2 watt resistors do I need for 3W power supply?

If the resistors have to handle 3 watts total, then each one has to be able to handle 1 watt. So those 1/2 watt resistors aren’t adequate. But you could use six 300 ohm 1/2 watt resistors. Thanks for contributing an answer to Electrical Engineering Stack Exchange!
