Question

an electric kettle connect to the 230v mains supply draws a current of 10. A calculated Related:  What is Electric Current (Ohms law, Resistance and Power) - Electricity, Class 10, Science

Answer

V= 230volt,
I=10A,
V=IR,
230=10(R),
R=230/10=23 ohm

Answer

Answer

Given

potential difference(V)=230v
current(I)=10A
By ohm's law
R=V/I
R=230/10
R=23ohm

Answer

Electric Current:

The electric current is the flow of electric charge through a conductor. It is measured in amperes (A) and is denoted by the symbol 'I'. The electric current is caused by the movement of electrons in a circuit.

Ohm's Law:

Ohm's Law is a fundamental principle in electrical circuits that relates the current flowing through a conductor to the voltage across it and the resistance offered by the conductor. It can be mathematically expressed as:

V = I * R

Where:
- V represents the voltage across the conductor,
- I represents the current flowing through the conductor, and
- R represents the resistance offered by the conductor.

Resistance:

Resistance is the property of a conductor that determines the amount of current flowing through it for a given voltage. It is measured in ohms (Ω) and is denoted by the symbol 'R'. Resistance can be affected by factors such as the length, cross-sectional area, and material of the conductor.

Power:

Power is the rate at which electrical energy is consumed or transferred in a circuit. It is measured in watts (W) and is denoted by the symbol 'P'. The power consumed by an electrical device can be calculated using the formula:

P = V * I

Where:
- P represents the power consumed,
- V represents the voltage across the device, and
- I represents the current flowing through the device.

Explanation:

In this scenario, an electric kettle is connected to a 230V mains supply and draws a current of 10A. Let's calculate the power consumed by the electric kettle.

Using Ohm's Law, we can rearrange the formula to solve for voltage:

V = I * R

Since we know the current (I) and voltage (V), we can calculate the resistance (R). However, the resistance of the kettle is not given directly, so we need to rearrange the formula:

R = V / I

Substituting the values, we get:

R = 230V / 10A = 23Ω

Now, we can calculate the power consumed by the kettle using the power formula:

P = V * I

Substituting the values, we get:

P = 230V * 10A = 2300W

Therefore, the electric kettle consumes a power of 2300W when connected to a 230V mains supply and drawing a current of 10A.

To summarize:

- Electric current is the flow of electric charge through a conductor.
- Ohm's Law relates the current, voltage, and resistance in a circuit.
- Resistance is the property of a conductor that determines the amount of current for a given voltage.
- Power is the rate at which electrical energy is consumed or transferred.
- The power consumed by an electrical device can be calculated using the formula P = V * I.
- In the given scenario, the electric kettle consumes a power of 2300W when connected to a 230V mains supply and drawing a current of 10A.
