This circuit diagram shows a baby Mr. Resistor with a 1V voltage source and unlabeled 1 ohm resistors. To find the Thevenin-equivalent circuit between terminals A and B, the equivalent resistance is 1/3 ohms, the equivalent voltage is 1/3 Volts, and the short circuit current is 1 Ampere.

1. please continue to get the answers in the bottom. Thanks! Below is a circuit of Mr. Resistor
when he was a baby. The voltage source is rated at 1 V and all unlabeled resistors are 1 Ohm.
Find the Thevenin-equivalent circuit with respect to terminals A and B.
Solution
Rth = 1/3 ohms
Vth = 1/3 Volts
Isc = 1A
