Estimate and record the reading uncertainties in your voltage , current and resistance measurements Record the value of each R, V and I in Figure 4 in the format , R:|: 5R (units ). Direction of the current: With each current measurement, note the direction of the current in the branch as shown in Figure 2, and mark it in Figure 4 with an arrow. 53 n | 5.?\" III F G \" Figure 4: A circuit to verify Kirchhoff's Rules
