🔍 Key Concepts

• Voltage gain definition (output vs. input) • Basic formula: Gain = Output Voltage / Input Voltage • How to rearrange the formula to solve for the unknown

💭 Think About

• If gain tells you how many times bigger the output is than the input, how can you express output in terms of input? • Once you have the formula with output and gain, how do you solve it to isolate the input voltage? • After you get the input value, which of the answer choices exactly matches it?

✅ Before You Answer

• Be clear whether gain multiplies the input or adds to it (it’s not addition). • Double-check your algebra when rearranging the gain formula. • Verify that your final input voltage, when multiplied by the given gain, gives the stated 30 V output.
