The more forward the bias is, the more the channel will be widened that is, the gate, which like a faucet valve, being more "open". The degree of which the Gate is being forward/reverse biased determines the input resistance of the FET.

If gate to source is opposite manner means forward biased then Will input resistance decrease?
