Op Amp is a Voltage Gain Device

Op Amp is a Voltage Gain DeviceOp amps are voltage gain devices. They amplify a voltage fed into the op amp and give out the same signal as output with a much larger gain. ... So the greater the resistance (or impedance) of a device, the greater the voltage drop across that device is.

Hope it's helpful for you...
