The heat produced in a conductor is proportional to the square of the current flowing through it, the resistance of the conductor, and the time for which the current flows. It is given by the formula H = I²Rt.

The heating effect of electric current refers to the phenomenon where heat is generated when an electric current flows through a conductor. This occurs due to collisions between electrons and atoms in the conductor.

Electric energy consumption is calculated using the formula E=P×t, where P is the power in watts and t is the time in hours. The result is typically measured in kilowatt-hours (kWh).

Power is the rate at which energy is consumed or produced, while energy is the total amount of work done over time. Power is measured in watts, and energy is measured in joules or kilowatt-hours.

In a series circuit, the current remains the same throughout all resistors, but the voltage is divided among them. In a parallel circuit, the voltage is the same across all resistors, but the current is divided among the different branches.
How do series and parallel resistors affect the current in a circuit?admin2024-11-13T01:43:54+05:30
In a parallel circuit, the current has multiple paths to travel through. Even if one of the resistors has a high resistance, the presence of other resistors provides additional paths for the current, reducing the total resistance.
Why is the total resistance in a parallel circuit always less than the smallest individual resistance?admin2024-11-13T01:43:37+05:30
When more resistors are added in parallel, the total resistance decreases because the current has more paths to flow through, reducing the overall opposition to current flow.
What happens to the total resistance if more resistors are added in parallel?admin2024-11-13T01:43:19+05:30
When more resistors are added in series, the total resistance increases because the current has to pass through each resistor, increasing the overall opposition to current flow.
