2ohms 4ohms 3ohms and 9ohms are connected across an 8-V DC source. what is the current through the 9ohm resistor
Another problem is
A 100 V DC signal is applied to four resistors. the values of the resistors are 20ohm 40ohm 60ohm and 80ohm. what is the voltage across the 40 ohm resistor.
They're kind of similar except one is current the other is voltage.
