Express your answer using two signiticant figures A battery with &-12.0 V and internal resistance r-1.0 is connected to two 65-kf2 resistors in series. An ammeter of internal resistance 0.60 measures the current, and at the same time a voltmeter with internal resistance 20 k measures the voltage across one of the 6.5-kS2 resistors in the circuit | (% diff) Submit My Answars Give Up Part D what is the % "error-from the vonage without meters? Express your answer using two significant figures. (% diff) Mty Answers Giee Up I'm Cortana. Ask me anything.

Explanation / Answer

without meter

I = 12/(13001) = 0.923 mA

with meters

the equivalent resistance is

Req = 6500+1.6 +20*6.5/(26.5) *1000 =11407.3 ohm

I' = 12/11407.3 =1.052 mA

the percentage difference is

(1.052-0.923)/0.923 = 14.0%

the voltage without meter is

v= 0.923mA*6.5 kohm = 6.00 V

with meters

v' = 1.052 mA* 4.906 kohm = 5.16 V

percentage difference is

(5.16-6.00)/6.00 = -14.0%
