Question: F.10

A relay’s contacts or a transistor’s collector–emitter can be used to create opens and shorts. Figure F–10(a) uses a relay to short one resistor in a series circuit (relay operation is described in Section 2–6). Sketch the waveform at Vout in Figure F–10(a). ...

Question: F.9

The symbol for a battery is seldom drawn in schematic diagrams. Figure F–9 is an alternative schematic for a series circuit. Solve for Vout. ...

Question: F.7

An open circuit is a break in a circuit. This can be done purposely by an electronic switching component, or it could be a circuit fault caused by a bad connector or burnt-out component. This break will cause the current to stop flowing to all components fed from that point. Calculate Vout in ...

Question: F.5

A short circuit occurs when an electrical conductor is purposely or inadvertently placed across a circuit component. The short causes the current to bypass the shorted component. Calculate Vout in Figure F–5. ...

Question: F.4

Use the voltage-divider equation to find Vout in Figure F–4. (Vout is the voltage from the point labeled Vout to the ground symbol.) ...

Question: F.3

series circuit has two or more resistors end to end. The total resistance is equal to the sum of the individual resistances (RT = R1 + R2). Also, the sum of the voltage drops across all resistors will equal the total supply voltage (VS = VR1 + VR2). Find the current in the circuit (I), the voltage ...

Question: F.1

(a) Determine the current (I) in the circuit of Figure F–1 if V = 10 V and R = 2 Ω. (b) Recalculate the current if R = 4 Ω. (c) Describe what happened to the value of the current when the resistance doubled to 4 Ω in (b). (d) Calculate the voltage required in Figure F–1 to make 2 A flow if R = 10 Ω ...
