Question

My (a) What is the terminal voltage (in V) of a large 1.50 V carbon-zinc dry cell used in a physics lab to supply 2.40 A to a circuit, if the cell's internal r is 0.200 ? 102 (b) How much electrical power (in W) does the cell produce? 3 60 (c) What power (in W) goes to its load? 1.15 Ea Reading capacitor and a variable resistor over what range in l The timin de ice in ar a ton o es termittent w pen ystem s based on an R t me constant and util zes a 0.345 be made to vary to achieve time constants from 1.50 to 19.0 s? smaller value 435 laraer value 55 0 Type here to search

Explanation / Answer

(c) Power into external circuit = [terminal voltage] * i

= (1.02 * 2.40) = 2.45 W

{The remaining power is dissipated in (r), warming up the dry cell.
