What is the current flowing through the resistor?

What is the current flowing through the resistor?

Current through each resistor can be found using Ohm’s law I=V/R, where the voltage is constant across each resistor. The current flowing from the voltage source in Figure 10.3. 4 depends on the voltage supplied by the voltage source and the equivalent resistance of the circuit.

What is the current flowing through the circuit?

If the two requirements of an electric circuit are met, then charge will flow through the external circuit. It is said that there is a current – a flow of charge. As a physical quantity, current is the rate at which charge flows past a point on a circuit.

What is the current flowing through the 2 W resistor?

Answer: The current through 2 ohm resistor is 2.1 A. Hence, the current through 2 ohm resistor is 2.1 A.

What is the current flowing through the 20 ohm resistor?

Since in parallel circuit, voltage is same across all resistors. Hence across the 20 ohm resistor, V=200V so I=200/20=10A. Current through 20 ohm equals 200 divided by 20 equals to 10 amp.

How do you measure the current through a resistor?

So the current through any resistor can be found by dividing the voltage across that resistor by its resistance. It’s not always possible to measure current through a circuit without disturbing it, so you measure the voltage drop across the resistor and calculate the current.

What would you do to measure the current in a resistor?

While there are several methods of measuring current, the most common method is to perform an indirect measurement by measuring the voltage across a precision resistor and using Ohm’s law to measure the current across the resistor.

What is a maximum voltage across a resistor?

The carbon film resistor has an operating temperature range of −55 °C to 155 °C. It has 200 to 600 volts maximum working voltage range. Special carbon film resistors are used in applications requiring high pulse stability.

How is the current across a resistor the same?

In a series circuit, the output current of the first resistor flows into the input of the second resistor; therefore, the current is the same in each resistor. In a parallel circuit, all of the resistor leads on one side of the resistors are connected together and all the leads on the other side are connected together.
