Poor communication: A leader who fails to communicate the company’s vision, goals, and expectations can create confusion on the team. Toxic leaders could also communicate negatively, such as insults, bullying, or belittling, which creates a toxic work environment. 2. WebNormally, the inner portion of the membrane is at a negative voltage. When that voltage becomes less negative and reaches a value specific to the channel, it opens and allows ions to cross the membrane ( Figure 12.5.4 ).

WebThe positive sign for current corresponds to the direction a positive charge would move. In metal wires, current is carried by negatively charged electrons, so the positive current arrow points in the opposite direction the electrons move. WebOct 12, 2024 · When crossing a resistor, the voltage change is determined by the formula: I*R where I is the value of the current and R is the resistance of the resistor. Crossing in the same direction as the current means the voltage goes down, so its value is negative.
