Ohm's Law in Series Circuits*

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor. It is expressed as V = I * R.

Current (I) can be calculated using the formula I = V / R, where V is the voltage and R is the resistance.

The unit of current is the Ampere (A).

The unit of voltage is the Volt (V).

The unit of resistance is the Ohm (Ω).

In a series circuit, the total resistance (R_total) is the sum of all individual resistances: R_total = R1 + R2 + R3 + ...

The total voltage in a series circuit is the sum of the voltages across each component: V_total = V1 + V2 + V3 + ...

In a series circuit, the current is the same through all components.

The voltage drop (V_drop) across a resistor can be calculated using Ohm's Law: V_drop = I * R, where I is the current through the resistor and R is its resistance.

In a series circuit, the voltage across each resistor is proportional to its resistance, and the total voltage is equal to the sum of the individual voltage drops.
