Yes, a single faulty or damaged electrical outlet can cause multiple downstream outlets on the same branch circuit to stop working entirely. Residential electrical wiring is typically installed using a daisy-chain configuration where power flows from the service panel into the first receptacle and then jumps across terminal screws to subsequent outlets in the room. If a terminal wire loosens, burns out, or detaches from a side screw on an active outlet, electrical continuity is broken for all subsequent receptacles downstream. You can troubleshoot power loss safely using a multimeter. You can verify that your corrective action is successful when isolating power, opening the suspect outlet box, and securing loose terminal wires restores full electrical voltage to every downstream outlet on the circuit.
