1. What do you use a voltmeter for? 2. What do you use an ammeter for? 3. What do you use an ohmmeter for?4. If you double the resistance in a circuit while keeping the current unchanged, what happens to the voltage? 5. Ifinstead, you keep the voltage unchanged, what happens to the current? 6. StateOhm’s law and sketch the relationship between voltage and current implied by Ohm’s Law.What is the slope of your curve and its SI unit
