LED flashlights use "white" LEDs which have a diode voltage drop of 4.0V. A LED flashlight has the circuit illustrated and will run off several AAA batteries that have a 1.5 VDC rating. a. What is the minimum number of AAA cells needed to turn on the flashlight. b. Would you arrange the batteries in parallel or in series? Vdd R + LED V fritzing

For the last two parts, use the diagram to the right. d. V = -1.14V, R = 62, and the voltage across the diode is equal to 0.68V when it is "on". i V = e. V = -0.16V, R = 52, and the voltage across the diode is equal to 0.64V when it is "on". V= i = Vo ww R≤ KHI (Enter at least 3 significant digits. Each answer must be within 1% to be marked correct.) + ひ -

After solving for the total resistance, and the applied voltage being a given for the circuit, the next logical step is to .....? so that individual component voltages and currents can be found.

Question 2: A) In the circuit shown in Figure 3, an uncharged capacitor with capacitance C and a resistor with resistance R are in series with a battery of emf E. E R swing C Figure 3. (i) After the switch has been closed for a very long time what is the final charge on the capacitor and what is the total energy stored in it? Solve in terms of E and C. (ii) When the power dissipated by the resistor is equal to ²/(25R), what is the energy stored in the capacitor? Solve in terms of E and C. (iii) Compute the time after the switch is closed when the charge on the capacitor is 4/9 of its final charge. Express your answers using E, C, and R, as appropriate.
