Just number 7-5 please. I just want someone to give me their answer so I can check if my answer is right
Assume there are 10 light bulbs that can be connected in series and 10 light bulbs that can be connected in parallel. Each bulb is rated 40 W. If the voltage at the plug is 220 V for both series and parallel connections, calculate the current through each bulb for both cases. Also find the voltage across each bulb.
When two resistors (RA and RB) are connected in series, the total resistance is 108 Ω. When connected in parallel, the equivalent resistance is 24 Ω. What the value of each unit is? Where RA > RB.
