What is electric current defined as?
The SI unit of electric current is:
According to Ohm's law, which formula is correct?
The SI unit of resistance is:
Sample Questions
Which materials are good conductors of electricity? (Select all correct answers)
Show answer
Copper, Silver, Aluminum
Metals like copper, silver, and aluminum are good conductors due to free electrons, while rubber and glass are insulators.
In a series circuit, the total resistance is:
Show answer
Equal to the sum of individual resistances
In series connection, total resistance R = R₁ + R₂ + R₃ + ..., as resistors are connected end-to-end.
Which factors affect the resistance of a conductor? (Select all correct answers)
Show answer
Length of conductor, Cross-sectional area, Material of conductor, Temperature
Resistance depends on length (R ∝ l), area (R ∝ 1/A), material (resistivity), and temperature. Color doesn't affect resistance.
Electric power is given by the formula:
Show answer
P = VI
Electric power P = VI, where V is voltage and I is current. This represents the rate of energy consumption.
