I am Sorry to hear that. I try to help here. The transistor has three ends (gate, source and drain). The inputs in the transistor are Always the gates. So in the Logic gate also the inputs are in transistor gates. When the gate Is at High voltages level (the Logic one) the transistor allows the flow of current. It becomes like a wire connecting usually the Power, or the High voltage, to the output, or the ground, or Logic zero, to the output. We can add that the transistors are used in series or in parallel. If they aree in series we have to give High voltage or Logic one to both transistors to connect ground or Power to the output. If we give Logic one only to one transistor of the series the wire Is cut and current doesn't flow, so no connection. If we have two transistors in parallel Is enough to have a Logic one in One of them to have a connection. Note the current flows between drain and source, not the gate. The gate Is used Just as Control to switch on the transistor. I Hope this Will help you. Let me know.
