The current through a resistor is 0.l ampere and the voltage across it is found to be 10.6 volts. What is the value of the resistor?

Draw a schematic circuit diagram of two resistors, each 100 ohms, in series with a 20 volt battery. Show a voltmeter connected to measure the voltage drop across the battery.

Draw a schematic circuit diagram of two resistors, 100 ohm and 200 ohm, connected in parallel with a 12 volt battery. Show an ammeter connected to measure the current through the 100 ohm resistor.
