Question 1
A technician needs to design a circuit that cannot exceed 2 amperes of current. If the available voltage supply is 24V, what resistance must be used?
💡 Hint: Rearrange the equation to solve for resistance.
Question 2
In a complex circuit, if one resistor has a resistance of 10Ω and another has 20Ω combined in series with a voltage of 30V, calculate the total current flowing through the circuit.
💡 Hint: Add the resistances together to find the total resistance first.
