Calculate the total resistance for two resistors: 5Ω in series with 10Ω. Then, if a total voltage of 15V is applied across this combination, find the current flowing through it.
💡 Hint: Remember to calculate total resistance first before applying Ohm's Law.
A household circuit includes three parallel resistors of 4Ω, 6Ω, and 12Ω. Calculate the equivalent resistance and then find the current if the voltage across the parallel combination is 24V.
💡 Hint: Use the reciprocal formula for parallel resistances to find total resistance.
