Aleks04 [339]
  1. A sketch of the junction between one chairlift and two runs is shown in the image attached below.
  2. For this ski resort, it ultimately implies that the total number of lifts that are used in any closed loop would be equal to zero in accordance with Kirchhoff's loop rule.

<h3>What is Kirchhoff's loop rule?</h3>

Kirchhoff's loop rule is also referred to as Kirchhoff's second law or Kirchhoff's voltage law, and it states that the algebraic sum of all the electric potential differences around any closed loop is equal to zero.

<h3>How to connect two runs in series?</h3>

Since the chairlifts are analogous to batteries, and the runs are analogous to resistors, the two runs would represent resistors that are connected in series with the lift, which represents the battery. Similarly, these three runs can also be connected in parallel by altering the positions of the runs with the battery.

For this ski resort, it ultimately implies that the total number of lifts that are used in any closed loop would be equal to zero in accordance with Kirchhoff's loop rule.

umka21 [38]

Answer:

1 DC

2 DC

3 DC

4 AC

5 DC

Explanation:

AC means alternating current this type of current is not constant I.e time varying

This type of current is being supplied from power lines

DC means direct current and flows at a constant direction. This type of current is being supplied from batteries.

brainly an electric heating element is connected to a 110V circuit and a current of 3.2A is flowing through the element. how muc
Naya [18.7K]

Energy used by the element = 6336000 j

The electrical energy is given by

E= V i t

V= voltage= 110 V

i= current=3.2 A

t= time= 5 h= 5 (3600)= 18000 s

so energy= E= 110 (3.2)(18000)

E=6336000 J
