A 0 – 150 voltmeter has a resistance of 2000-ohms per volt.  It is desired to change this voltmeter to a 0 – 600 volt instrument by the edition of an external multiplier. What is the resistance, in ohms, of this external multiplier?

C -Q (A) 0.25 uF 10V 2uF 4uF (B) Figure 3: 3. In Figure 3 the capacitors were discharged before being connected to the battery. (a) In Figure 3A the net positive charge delivered by the battery is +Q1 to C1 and a net negative charge -[Q2 + Q3] is delivered to C2 and C3 [-Q2 is delivered to C2 and -Q3 to C3]. From conservation of charge[net charge is zero since both the battery and the capacitors have a zero net excess charge] and path independence of the electric field[sum of voltages must add up to zero for a closed path or conservation of energy]: Q1 + (-Q2) + (-Q3) = 0 conservation of charge +%-왕-용 (True, False) = 0 conservation of energy +V - = 0 conservation of energy (b) If (a) is true then the charge Q1, Q2 and Q3 follow from above three equations as C1(C2 + C3) V Q2 = Ci + C2 + C3 C1 C3 Ci + C2 + C3 Q1 = Q3 = V, (True, False) C1 + C2 + C3 (c) In Figure 3A the net positive charge delivered by the battery is Qtot = Q1 = C1(C2+C3) v which implies an equivalent capacitance of Qtot…

For the following circuit, the diodes are silicon with a forward barrier voltage of 0.7-V. Calculate ID, ID2, D3, and VA using the following steps: ↓ +5 V ww R₁ = 5kQ VA D₁ D₂7 IDI R, = 5 kΩ -10 V 11p2 ID3 -5 V D3 VB R3= 5 kQ2 ↓ a) Assume all of the diodes are forward-biased and conducting. Redraw the circuit. Therefore, ideal voltage sources can be substituted for ID₁, D₂ and ID3. What are the values of V₁ and V?
