challenging questions reveals where you need to focus your study efforts Lets Get Started Basic Electrical Engineering Questions This section focuses on core concepts applicable to both electrical and electronics engineering Well cover topics like Ohms Law Kirchhoffs Laws and basic circuit analysis 1 Ohms Law Question A resistor has a voltage of 12V across it and a current of 2A flowing through it Calculate its resistance Answer Using Ohms Law V IR Resistance R VI 12V 2A 6 2 Visual Imagine a simple circuit with a battery 12V a resistor 6 and an ammeter measuring 2A The current flows from the positive terminal of the battery through the resistor and back to the negative terminal Insert a simple circuit diagram here showing a battery resistor and ammeter 2 Kirchhoffs Laws Question Apply Kirchhoffs Voltage Law KVL to find the voltage across R2 in the following circuit Insert a simple circuit diagram with two resistors in series connected to a 10V battery Answer KVL states that the sum of voltages around a closed loop is zero Therefore Vbattery VR1 VR2 0 Youll need the values of R1 and R2 to solve for VR2 This requires further calculation depending on the values of R1 and R2 provided in the diagram Visual Highlight the loop in the circuit diagram indicating the direction of current flow and voltage drops across each resistor Insert the same circuit diagram as above with annotations highlighting the voltage drops and current flow 3 Basic Circuit Analysis Question Calculate the total resistance and current in a parallel circuit with two resistors R1 10 and R2 20 connected to a 15V battery Answer For parallel resistors the total resistance Rt is calculated as 1Rt 1R1 1R2 Once you find Rt use Ohms Law I VRt to calculate the total current Visual Show a parallel
