Time constant of rc circuit experiment

05/05/2021 Client: muhammad11 Deadline: 2 Day

Physics Laboratory Manual n L ABOR AT ORY Loyd 33 The RC Time Constant OBJECTIVES o Investigate the time needed to discharge a capacitor in an RC circuit. o Measure the voltage across a resistor as a function of time in an RC circuit as a means to determine the RC time constant. o Determine the value of an unknown capacitor and resistor from the measurements. EQUIPMENT LIST . Voltmeter (at least 10 MO resistance-digital readout), laboratory timer . Direct current power supply (20 V), high quality unknown capacitor (5–10 mF) . Unknown resistor (approximately 10 MO), single-pole (double-throw) switch . Assorted connecting leads THEORY Consider the circuit shown in Figure 33-1 consisting of a capacitor C, a resistor R, a source of emf ", and a switch S. If the switch S is thrown to point A at time t ¼ 0 when the capacitor is initially uncharged, charge begins to flow in the series circuit consisting of ", R, and C, and it flows until the capacitor is fully charged. The current I has an initial value of "/R and decreases exponentially with time. The charge Q on the capacitor begins at zero and increases exponentially with time until it becomes equal to C". The equations that describe those events are COPYRIGHT ª 2008 Thomson Brooks/Cole Q ¼ C" ð1 # e#t=RC Þ and I ¼ "=R e#t=RC ðEq: 1Þ The quantity RC is called the time constant of the circuit, and it has units of seconds if R is in ohms and C is in farads. After a period of time that is long compared to the time constant RC, the charge Q is equal to C", and the current in the circuit is zero. If switch S is now thrown to position B, the capacitor discharges through the resistor. The charge on the capacitor and the current in the circuit both decay exponentially while the capacitor is discharging. The equations that describe the discharging process are Q ¼ C" e#t=RC and I ¼ "=R e#t=RC ðEq: 2Þ ª 2008 Thomson Brooks/Cole, a part of TheThomson Corporation.Thomson,the Star logo, and Brooks/Cole are trademarks used herein under license.

R Figure 33-1 Simple series RC circuit. The current in the discharging case will be in the opposite direction from the current in the charging case, but the magnitude of the current is the same in both cases. Consider the circuit shown in Figure 33-2 consisting of a power supply of emf ", a capacitor C, a switch S, and a voltmeter with an input resistance of R. If initially the switch S is closed, the capacitor is charged almost immediately to ", the voltage of the power supply. When the switch is opened, the capacitor discharges through the resistance of the meter R with a time constant given by RC. With the switch open, the only elements in the circuit are the capacitor C and the voltmeter resistance R, and thus the voltage across the capacitor is equal to the voltage across the voltmeter. It is given by V ¼ " e#t=RC ðEq: 3Þ Rearranging and taking the natural log of both sides of the equation gives Inð"=VÞ ¼ ð1=RCÞt ðEq: 4Þ If the voltage across the capacitor is determined as a function of time,
