Find the equivalent resistance, the current supplied by the battery and the current through each resistor when the specified resistors are connected across a 2-v battery. part (a) uses two resistors with resistance values that can be set with the animation sliders, and you can use the animation to verify your calculation. in part (b), three resistors are specified.

(a) two resistors are connected in series across a 2-v battery. let r1 = 10 ? and r2 = 9 ? .
req = ?
i = a
? v1 = v
? v2 = v

(b) add a third resistor to the circuit in series. let r1 = 10 ? , r2 = 9 ? , and r3 = 3 ? .
req = ?
i = a
? v1 = v
? v2 = v
? v3 = v

Answer with Explanation:

We are given that

Potential difference =2V

a.

We know that in series

b.

answer: option c. i.e. electric current flowing “downhill” from the negative electrode to the positive electrode in a battery

explanation:

the water analogy to the circuits define the pipes (water flows) to the electric current. now, we know that the electric current flows from the positive terminal to the circuit (as shown in the diagram attached).

hence, option c is the correct answer.

-first use of geothermal energy occurred more than 10,000 years ago in north america by american paleo-indians

-the first industrial use of geothermal energy began near pisa, italy in late 18th century

-in 1904, italian scientist piero ginori conti invented the first geothermal electric power plant in which steam was used to generate the power

-with the above experiment, the first geothermal plant in usa started in 1922 with a capacity of 250 kilowatts

-however, in 1946 first ground-source geothermal heat pump installed at commonwealth building in portland, oregon

-during the 1960’s, pacific gas and electric began operation of first large scale geothermal power plant in san francisco, producing 11 megawatts

-in 1973, when oil crisis began many countries began looking for renewable energy sources and by 1980’s geothermal heat pumps (ghp) started gaining popularity in order to reduce heating and cooling costs

-as effect of climate change started showing results, governments of various countries joined hands to fight against it, for which kyoto protocol was signed in japan in 1997, laid out emission targets for rich countries and required that they transfer funds and technology to developing countries, 184 countries have ratified it
