... 8. E = 18V. R1 = 9 MΩ. R2 = 1 MΩ. A student uses a voltage divider in hopes of converting 18 V to 2 V, using the circuit shown. When the student connects a cheap volt-ohm meter (VOM) to Vout, she gets just 1.75 V. Explain why the voltage is lower than expected. Note: This problem has nothing to do w ...
