Question

With the given information, what are the following values?
Also, sorry for the picture quality. it was the best I could do.

Parallel Circuit Voltage V Total current A Observed total Ω Theoretical Rotal 12 Do the observed results agree reasonably with the experimental value? 1. A 12 A Do the currents through the individual resistors agree with the total current according to the equations given?

The voltage is 0.528 V(in volts) and the current is in amperes. However, I think it needs to be converting to mA. So, I believe the current is 0.1483 mA, 0.0925 mA, 0.00498 mA.

Answer 1

Solution ; are in case 1: When E=Ri and F-R2 parallel combination Volt Voltage 00528 Total current 148.3 MA = 148.3 x 10-3 A. Rtotal, law ohn's observed Now, from Rtotal Voltage Total Current 0.528 Volt 14803 X10-3 A 3.58 and nesistors only across both in E=Ri Voltage case 2: current Volt 0.528 9205 X10-3 A Voltage current = 9 205 mA E, of resistance valves i sor -22 Voltage current 0.528 25.71 92.5 X10-3 R,

Case 8 and Voltage across both current through F resistors only. Voltage Current 0.528 Volt 49.8 mA 49.8 X10-3 A. resistance :: value of F, Noltage 2 z 10.60 2 S مه 0.528 49.8 x10-3 current ape in parallel resistance com bination of their Nowi E and Hence, theonitical total parallel combination, Rtotal Ri R2 Rit R₂ 2 5.71 X 10.60 5071 +10.60 3.712 Rtotal When measure once that also we . . Now, observed = 3.57-2 and theonitical Rtotal = 3.712 are nearly equal. A small difference intro duced because observed Rtotal = 3.50-2 wines we connects Volfmeter and Ammeter Rtotal includes some resistance of wires and introduced calculation when theonitically calculate we resistance measurement Thats' Why 3.712 greater the in for Ri we wires Buti RiR2, introduced Rtotal Ritra twice, Once and once for R measune. R total is slighity that. observed 3058 22 Rtotal

I= 149.3 mA # Is For Gase 1 : For Gase 2 : total current I= 148• 3 4. total current, I = 9205 mA total current, I2 4908 mA. For case 3 i to theory, so, according I- + Iz Il 14203 mA 0574918 ) ma But, IstI= of not and addition addition corrent current so, total individual are same.
