Electrical Circuit Analysis: Understanding Voltage and Resistance

What is the voltage across the 1200 ohm resistor?

Final answer: 72 V

Answer:

The voltage across the 1200 ohm resistor is 72 V.

Understanding the voltage across a resistor in an electrical circuit is crucial for circuit analysis. In this case, the voltage across the 1200 ohm resistor is given as 72 V. This value is determined by the current flowing through the resistor and the resistance value itself.

When dealing with resistors in a circuit, Ohm's Law is a fundamental principle that can be used to calculate voltage, current, and resistance. Ohm's Law states that V = IR, where V is the voltage, I is the current, and R is the resistance.

For the 1200 ohm resistor in this scenario, the voltage of 72 V is calculated by multiplying the current flowing through the resistor by the resistance value. By knowing the value of the resistor and the current, we can accurately determine the voltage across the resistor.

Understanding how voltage and resistance interact in an electrical circuit is essential for analyzing and troubleshooting circuit behavior. By applying principles like Ohm's Law, we can calculate and predict various electrical quantities in a circuit.
