PRE-LAB PREPARATION SHEET FOR LAB 6-VOLTAGE IN SIMPLE DC CIRCUITS AND OHM\'s LAW

Question

PRE-LAB PREPARATION SHEET FOR LAB 6-VOLTAGE IN SIMPLE DC CIRCUITS AND OHM's LAW (Due at beginning of lab) Directions: Read over Lab 6 and then answer the following questions about 1. What d o you predict for the brightness of the bulbs in Figure 6-la and inresses Figure 6-1c2 2. What do you predict for the brightness of the bulbs in Figure 62 and Figure 6-la? How will you measure the voltages between points 1 and 2 in the three cir- cuits shown in Figure 6-3? What equipment will you use? 3. What do you predict will happen to the voltage across the battery in Figure 6-7a when you close the switch? 4. 5. What is the function of the power supply in Figures 6-12 and 6-13 How will you determine the quantitative relationship between the voltage across a resistor and the current flowing through it? What equipment will you use? 6.

Explanation / Answer

6) the relation between voltage, current and resistance is

V=IR

which is known as ohm's law.

For measuring the values of voltage and current at different resistances, you can use voltmeter and ammeter.

voltmeter is connected in parallel to your voltage source whereas ammeter is connected in series with your circuit.
