A) True
B) False
3. For three resistors connected in series, the voltage across each resistor is equal even if the resistors have different values.
A) True
B) False
----
For number 1, I guessed True. I'm not sure but my reasoning behind is by KCL and KVL, voltages around a loop and current entering a node is zero at every instant. Again, I'm not sure about this one.
For number 2, I guessed False. The cicuit on the left, I used Ohm's law to find its voltage; 50(v). On the other hand, the right circuit doesn't have a resistor at all. So I thought since 50(v) is greater than 0 (v) {the right circuit}, the statement is false, which states two circuits are equivalent.
For number 3, I guessed True, because by the definition KVL, the sum of voltages around a loop equals zero.
I'm confident about my answer for number 3, but I'm doubtful about 1 and 2.
