The International System of Units (SI) is the modern metric system used to measure various physical quantities, including those related to electricity. Here are some basic concepts and units related to electricity in the SI system:
Electric Charge (Q):
Unit: Coulomb (C)
1 Coulomb is the amount of electric charge transported by a current of 1 Ampere in 1 second.
Current (I):
Unit: Ampere (A)
1 Ampere is the current flowing through a conductor when a potential difference of 1 Volt is applied across it.
Voltage (V):
Unit: Volt (V)
1 Volt is the potential difference across a conductor when a current of 1 Ampere flows through it.
Resistance (R):
Unit: Ohm (Ω)
1 Ohm is the resistance of a conductor in which a potential difference of 1 Volt produces a current of 1 Ampere.
Power (P):
Unit: Watt (W)
1 Watt is the rate at which work is done or energy is transferred when a current of 1 Ampere flows through a potential difference of 1 Volt.
Energy (W):
Unit: Joule (J)
Energy is the capacity to do work or produce heat. It's related to power and time by the equation: Energy (J) = Power (W) × Time (s).
Frequency (f):
Unit: Hertz (Hz)
Frequency refers to the number of cycles (oscillations) per
