Question

Hello,

I only need part D and E. Show all work for those two parts.

In the figure below, R1-6.50 Ω and R2-R,-R4-26.0 Ω" The battery has an emf of ε-120 V. R1 Ry a.) How much energy is dissipated by all four resistors in one minute? Inserting a measurement device into a circuit to figure out what it's doing will actually affect what it's doing- you cannot measure anything for free". While we generally hope the effect is negligible, we will explore this below. To make sure the effects aren't lost in the round-off, we will exaggerate them by using "Cheap-Co" brand measurement devices. b.) First, calculate the theoretical baseline values for the current and voltage for R1, before any measurement devices are inserted. (Recommended: Find to at least 3 decimal places so you can accurately gauge small changes to them in subsequent parts.,) V1-51.4 С.) An ammeter (internal resistance of 2 Ω) is connected properly in series with R1, what effect will that have on the value you are trying to measure? 11 will decrease by 0.920 Also, what happens to the total current flowing out of the battery? decreases d.) Suppose instead a voltmeter (internal resistance of 130 Ω) is connected properly in parallel with R1, what effect will that have on the value you are trying to measure? V1 will decreaseby Also, what happens to the total current flowing out of the battery? increases e.) Suppose you accidentally hooked up your ammeter improperly in parallel with R What value would it measure n 1 ow? I measured by ammeter. X A What is the actual current flowing through R1? actual 11 =

Note: the last question in part (e) asks for the I measured by ammeter, and actual I1
