Don't we need some more information?
What is the power supply (and if it's AC, what is the frequency)?

A circuit is an electrical network that allows the flow of electric current. We need to find the voltage across its components in order to understand how the circuit is functioning, and to determine the amount of energy being used or stored in each component.
To find the voltage across a resistor, you can use Ohm's Law (V=IR), where V is the voltage, I is the current flowing through the resistor, and R is the resistance of the resistor. You can also use Kirchhoff's Voltage Law (KVL) to calculate the voltage across a resistor by summing the voltage drops in a closed loop in the circuit.
The voltage across a capacitor is different from a resistor because a capacitor stores electrical energy, while a resistor dissipates it. This means that the voltage across a capacitor is directly proportional to the amount of charge stored on it, while the voltage across a resistor is directly proportional to the current flowing through it.
The voltage across an inductor changes with time in a circuit because an inductor resists changes in current flow. When the current changes, the inductor creates a magnetic field that opposes the change in current, resulting in a change in voltage. This can be calculated using Faraday's Law (V=L(di/dt)), where V is the voltage, L is the inductance of the inductor, and di/dt is the rate of change of current.
Finding voltage across circuit components is important in many practical applications, such as designing and troubleshooting electronic circuits, analyzing power consumption in electrical systems, and designing efficient power supplies. It is also crucial in industries such as telecommunications, power generation, and automotive engineering.
