How is battery defined under the Penal Code?

Battery is defined under the Penal Code as the unlawful use of force resulting in injury. This definition captures the key elements of battery: it involves an intentional action where one person uses physical force against another, which leads to some form of injury or harm. This can include anything from physical harm, such as bruises or cuts, to more serious injuries that require medical attention.

Understanding this definition is crucial, as it distinguishes battery from other related offenses. For instance, emotional distress or fear of harm may relate to other crimes like assault or intentional infliction of emotional distress, but those do not involve the actual use of physical force that results in injury.

Additionally, while an unlawful act against a person encompasses a broad range of actions, battery specifically requires a combination of intent and injury, making option B the most precise and accurate definition of battery within the Penal Code.
