PHYS

• A junction where 2 or more elements connect is called a Node.
• These connections between nodes that can be a resistor, capacitor, etc. are called branches.
• The number of branches is equal to the number of elements.
• A loop is a closed path going through circuit elements.
• In Kirchhoff's Law of Voltage, the sum of voltages around a loop is zero.
• Closing the switch allows the capacitor to charge.
• Magnetism is the force exerted by magnets when they attract or repel each other.
• Like poles repel, opposite poles attract.
• Electric charge creates electric field E.
• The magnitude is equal to the magnitude charge (magnitude increases, magnitude charge also increases, vice versa).
• A charged particle at rest experiences no magnetic force.
• Gustav Kirchhoff is a German physicist.
• A charged particle whose velocity is perpendicular to the field direction will follow a circular path.
• The magnitudes of v(velocity) and F(force) are constant.
• Repulsion - Opposite direction
• Attraction - Same Direction
