The relationship between current, voltage, and resistance is described by Ohm's Law. It states that the current flowing through a conductor is directly proportional to the voltage applied and inversely proportional to the resistance of the conductor. This can be represented by the equation I = V/R, where I is current in amperes, V is voltage in volts, and R is resistance in ohms.
The unit of measurement for current is amperes (A), voltage is volts (V), and resistance is ohms (Ω).
A resistor is a passive component that resists the flow of electric current in a circuit. It reduces the amount of current that can flow through it, thus controlling the flow of electricity and reducing the voltage. The higher the resistance of a resistor, the lower the current will be.
Yes, current and voltage can affect the resistance of a material. As the current increases, the resistance of a material also increases. Similarly, as the voltage increases, the resistance of a material also increases. This is because the flow of electrons is impeded by the resistance, resulting in a decrease in current.
In a series circuit, the current flowing through each component is the same, and the voltage across each component adds up to the total voltage of the circuit. The total resistance in a series circuit is equal to the sum of individual resistances. This can be represented by the equation V = IR, where V is voltage, I is current, and R is total resistance.
