Quick questions on Amplifier basics and gain - WJEC GCSE Electronics (7)

3short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.

What are not converting voltages?

Show answer

Put both voltages in the same unit (for example volts) before dividing in

G = \dfrac{V_{\text{out}}}{V_{\text{in}}}

What is q1?

Show answer

An amplifier gives an output of

4.0\,\text{V}

for an input of

25\,\text{mV}

. Calculate the voltage gain. [2 marks]

What is q2?

Show answer

State what happens to the peaks of an amplifier's output if the gain is increased far beyond the supply limit. [1 mark]
