Answer:
Series combination:
Equivalent resistance =10Ω
Parallel combination:
Equivalent resistance
Explanation:
Resistance: Resistance is the ratio of voltage to the current.
R = resistance
I = current
V= potential difference(voltage)
There are two types of resistance combinations.
- series combination
- parallel combination.
Series combination: If the ending point of one resistance is connected to the starting point of other resistance that combination is known as series combination.
If R₁,R₂ and R₃ are connected in series combination.
Then equivalent resistance = R₁+R₂+R₃
Parallel combination: If the ending point and the starting point of the all resistance are the same points that combination is known as parallel combination.
If R₁,R₂ and R₃ are connected in parallel combination.
Then equivalent resistance
Here R₁=7Ω and R₂=3Ω
If R₁ and R₂ connected in series combination
Then equivalent resistance = (7+3) Ω
=10Ω
If R₁ and R₂ connected in parallel combination
Then equivalent resistance
Answer:
1) Yes the direction of the magnetic field is found based on Fleming's Right Hand Rule
2) The pattern indicates the direction of the magnetic force field lines
Explanation:
1) The solenoid is the is the coil of electric conductor that when it carries an electric current produces a magnetic field
According to Fleming's Right Hand Rule, the direction of the magnetic field produced by a solenoid, depends on the direction of the current such that when the direction of the conventional current is in the direction of the wrapped fingers, the thumb points in the direction of the magnetic field which is North N.
2) The pattern of field lines inside the solenoid indicates the direction of the generated magnetic field moving from left to right within the solenoid as the electric current moves around in the direction shown in the diagram.
